People who scored high for antagonistic traits are more likely than agreeable people to have thickening of the carotid arteries, a risk factor for cardiovascular illnesses, an Italian study showed. Researchers also found that while men generally had more thickening of the artery walls than women, the risk of arterial thickness in antagonistic women was comparable to that in antagonistic men.
Medical procedures make up 98% of all artificial radiation sources worldwide, according to a report from the United Nations Scientific Committee on the Effects of Atomic Radiation. CT scans were the major sources of radiation, but other procedures, such as X-rays and nuclear medicine tests, also contributed to radiation exposure, the report said.

A generic diuretic proved to be as effective as an expensive calcium-channel blocker or angiotensin-converting enzyme inhibitor in preventing cardiovascular disease during a long-term study. However, patients who received an ACE inhibitor or a calcium-channel blocker had a 20% and 12%, respectively, higher death rate caused by stroke or heart failure compared with those on a diuretic.
The National Research Universal reactor in Chalk River, Canada, has restarted and is expected to alleviate the shortage of the medical isotope molybdenum-99. SNM, however, warns that the Canadian government is likely to close the reactor for good in 2016. The society is calling for the passage of the American Medical Isotopes Production Act, which would allow for the domestic production of isotopes.
The American Medical Isotopes Production Act, which is being blocked in the Senate by Sen. Christopher Bond, R.-Mo., and which would allow for the domestic production of isotopes using low-enriched uranium, needs to be passed by the Senate before its session ends, according to this New York Times editorial. Bond's argument that the bill could lead to isotope shortages is flimsy and contradicts the judgment of medical groups that require the isotopes most, the editorial said.
